RAILWAY-RAIL.

SPECIFICATION forming part of Letters Patent N 0. 727,288, dated May 5,1903.

Application filed October 9, 1902.

To all whom it may concern.-

Be it known that I, GEORGE ANSON CASE, a citizen of the United States,and a resident of Joplin,in the county of Jasper and State of Missouri,have invented a new and Improved Railway-Rail, of which the followingisa full, clear, and exact description.

This invention relates to a sectional rail; and it constitutes animprovement over the constructioncovered in my prior patent, No.

(592,115, dated January 28, 1902.

The present invention is directly concerned with the base or mainsection ofthe rail; and the object is to construct this section tubular,so that compressed air or fluids of any sort may be transmitted throughthe rail without interfering with the use of the rail in its ordinarycapacity.

This specification is an exact description of one example of myinvention, while the claims define the actual scope of the invention.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding'parts in all the views.

Figure 1 is a side elevation of the invention. Figs. 2, 3, andarerespectively crosssections on the lines 2 2, 3 8, and 4:4: of Fig. 1;and Fig. 5 is a detail view of the detachable cap or ball section of therail.

The base or main section of the rail cornprises a base proper, a-,a weba, and a ball a 19 indicates the removable ball or cap, having the sideflanges or skirts b, and 0 indicates the fish-plates, with the tongues-cinterengaged with the cap I) in the manner described in my previouspatent above referred to. The main part of the rail is constructedtubular of pressed or rolled steel, either with a welded joint or ofseamless tubing, as may be desired. The bolts d, which fasten thefishplates 0 in place pass through the web a of the main portion of therail, and in order to prevent leakage at these points the web a isswaged in, asindicated at a and these swaged portions are welded orotherwise hermetically fastened together. Such swaged portions areindicated in Fig. 4 and by the dotted Serial No. 126.463. (F0 model.)

lines in Fig. 1. It will be seen from this that the bolts 01 may beplaced in position without any means of packing with which to preventleakage, since owing to the swaged and welded parts a the compressedair, liquid, or other fluid will not reach the orifices in the railVarious changes in the form, proportions, and minor details of myinvention may be resorted to without departing from the spirit and scopethereof. Hence I consider myself entitled to all such Variations as maylie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A tubular rail, havinga transverse openingtherein, said rail being hermetically closed around the sides of saidopening to prevent leakage therethrough. r

2. A tubular rail for the purpose specified,

said rail having parts swaged inward and hermetically connectedtogether, and the rail also {having a transverse opening formed thereinat said swaged portion.

3. A tubular rail for the purpose specified, said rail having its sideportions at the web swaged inward toward each other and welded together,and the rail also having a transverse opening passed through said swagedportions.

ft. The combination of a tubular main railsection having parts of itsside portions swaged inward and hermetically connected together and alsohaving an opening passing through said swaged portions, fish-plateslying'against the sides of the main rail-section, a bolt passing throughthe fish-plates and through said opening in the main railsection, and aremovable ball or cap placed on the main rail-section and engagedwiththe fish-plates.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE ANSON CASE.-
